\r\n \r\n Brain scans can find evidence of Alzheimer\'s a decade or more before it causes memory and thinking problems, but they\'re too expensive and impractical for routine use. A simple eye test and warning signs like falls could be a big help.
\n
\nThe eye study involved photographing blood vessels in the retina, the nerve layer lining the back of the eyes. Most eye doctors have the cameras used for this, but it takes a special computer program to measure blood vessels for the experimental test doctors are using in the Alzheimer\'s research, said the study\'s leader, Shaun Frost of Australia\'s national science agency, CSIRO.
\n
\nResearchers compared retinal photos of 110 healthy people, 13 people with Alzheimer\'s, and 13 others with mild cognitive impairment, or "pre-Alzheimer\'s," who were taking part in a larger study on aging. The widths of certain blood vessels in those with Alzheimer\'s were different from vessels in the others and the amount of difference matched the amount of plaque seen on brain scans.
\n
\nMore study is planned on larger groups to see how accurate the test might be, Frost said.
\n
\nEarlier work by Dr. Lee Goldstein of Boston University showed that amyloid, the protein that makes up Alzheimer\'s brain plaque, can be measured in the lens of the eyes of some people with the disease, particularly Down syndrome patients who often are prone to Alzheimer\'s.
